CRUST CRUSHER FOR BEE'I' CULTIVATORS.

Application filed March 9, 1928. Serial No. 260,511.

This invention relates to a crust crushing attachment for cultivators, the general object of the invention beingto provide a wheel carryi ng a plurality of spikes, with means for yieldingly supporting the wheel from a part of the cultivator so that the spikes on the wheel, penetrating the ground, will break up the crust which forms after a rain, the yieldable supporting means allowing the wheel to adjust itself to variations in the ground level.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereii'iafter fully described, illustrated in the accompanying drawin and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accon'lpanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side view of the attachment, the bars of the cultivator to which the atta elnnent is connected being shown in section.

Figure 2 is a front view showing the device attached to parts of the cultivator.

Figure 3 is a sectional view through the device.

Figure 4 is a view of one of the supporting rods for the wheel.

Figure 5 is a detail sectional view showing howthe spikes are supported in the wheel.

In these views, the numeral 1 indicates a pair of bars which are adapted to be connected with the beams 2 of a cultivator by the clamps 3. Each bar is provided with a number of notches 4 for receiving portions of the clamping means so that the bars can be adjusted longitudinally. The lower end of each bar is formed with an elongated slot 5 to receive the bolt or shaft 6 which passes through the hub 7 of the wheel 8. The hearing blocks 9 for the ends of the shaft are fastened to the lower ends of the rods 10, the upper ends of which pass through holes in the brackets 11 fastened to the bars 1. A coil spring 12 is placed on each rod and bears against the block and the bracket and tends to press the shaft toward the lower ends of the slots 5, but enables the Wheel to adjust itself to variations :in the surface of the ground. The tension of the springs can be adjusted by placing the pins 13, which hold the rods in the brackets, in any one of a number of holes 14 formed in the upper end of the rod.

The rim of the wheel is provided with a plurality of holes 15 for receiving the stems 16 of the spikes 17, these spikes being held in place by the washers l8 and the nuts .19 placed on the stems. The bushing of the hub and the shaft can be lubricated through means of the cup 20.

From the foregoing .it will be seen that when a cultivator, provided with one or more of these attachments, passes over the ground. the spikes on the wheel will break up the hard surface or crhst which forms after a rain and by yieldingly supporting the wheel through means of the s ')rings and the slotted bars 1, the wheel can adjust itself as it passes over an uneven surface.

While the device is mainly designed for use with beets for breaking the crust formed before the young plants come through the ground, it will. of course, be understood that the device can lie used for other purposes.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

hat I claim is An attachment for a cultivator con'uarising a. pair of depending bars each bar having notches in one of its edges at its upper end. means for clamping the upper ends of the bars to a part of the cultivator said clanuaing means having projections thereon for engaging some of the notches, the lower ends of the bars having elongated slots therein, a shaft passing through the slots, a wheel carried by the shaft, bearing blocks through which the ends of the shaft pass, an upright rod con nected with each block, a bracket on each bar having a hole therein through which the rod passes, a spring on each rod between the bracket and the bearing block and spikes carried by the rim of the wheel, sa i d spikes h aving threaded shanks passing through holes in the rim and nuts engaging the slnmks for detachably holding the spikes to the rim.

In testimony whereof I afliX my signature.

BARENT O. JEPPSON.
